Kant: Conditioned and Unconditioned Acts of Will (revised) -- by Gordon
Ziniewicz

Interest (Heteronomy): Will is moved by something
outside of itself, including one’s own feelings.

1. Since my friend is depressed right now (condition) because her husband
has left her for a younger woman (condition) and since I want to help
her (inclination), I will lie to her (act) about what I heard her husband
say, so that she will be able to pull herself together for the time being
(consequence).

<--- In this case, the will is moved by something outside
of will (condition or inclination or interest or consequences): The will
is determined, heteronomous. It acts in accordance with an hypothetical
imperative. The will is conditioned; it takes orders from things outside
of the will.

Duty (Autonomy): Will is “self-moving,”
not moved by anything outside of itself, including emotion.

2. Even though my friend is depressed right now (condition)
because her husband left her for a younger woman (condition) and despite
the fact that I want to help her (inclination), I will not lie to her (act)
about what I heard her husband say, because it is always wrong to lie no
matter what the consequences (respect for universal moral law).

<--- In this case, the will moves itself out of duty or
out of respect for the universal moral law, does what is right simply because
it is right: The will is free, autonomous. It acts in accordance with a
categorical imperative, which it determines for itself and commands itself
to obey. The will is un-conditioned; it takes orders from itself alone.
